Building Energy Rating Guide

The energy performance certificate reflects the heating efficiency and energy consumption intensity of the building.

C · this building Energy Efficient Good standard efficiency

Key Risk Factors

  • Built in 2008: technical utility systems require periodic updating and capital maintenance.
  • Energy class C: typically average heating demand. The energy certificate has expired, so the current class may differ. Actual heating costs depend on the apartment and how it is used.
  • Parking: on-grade surface parking on parcel/street; no separate underground garage.
  • Valuation nuance: bank collateral value for a specific unit depends fundamentally on interior finish.

Figures refresh with every data load and each states its period and sample — see the methodology.

Building data reconciled against the EHR and Land Board (Maa-amet) registries. AVM methodology by Martin Koppel, Estiq real estate valuation advisor (methodology aligned with the EVS 875 standard). This is an automated model estimate, not an EVS 875 appraisal report. Updated 20.10.2026.
